"That is, when the helper'iis'moved upwardly as hereinafter mentioned,the engaging por- Tao tion 14 becomes, in a sense, an integral part ofthe needle itself. Therefore, obviously unless the body engaging portion15 is lengthened, there will be no balance between the portion 14. andneedle and the portion 15,

which will be detrimental to the smooth and balanced operationol themechanism" as a" whole.

It will be noted are substantially H-shaped. It may. here be statedothatthe jacquard card-engaging portions of the helpers 12 and13 have herebeen designated by reference characters 18 and 18, respectively. Thehelpers 12 and" 13 may be quite conveniently andeconomically fabricated bystamping; the same, bymeans As clearlyillustratedin the variouslfiguresof the drawing, the jacquard.card-engaging portions 18 oftheneedlehelpers 12,00111- prising one of the two serieszof needlehelpers, are staggered or displaced with" re-.

spect to the jacquard cardengaging portions 18" of theremaining needlehelpers 13, comprising the alternately d sposed series of needlehelpers; It will be notedqethat by.

means of this arrangementsufficient space 1s provided for the accurateand certain operation of theneedle helpers 12 and 1 8, which, arealternately disposed with respect; to each other, withinthe respectivegrooves 11 of the auriliaryor other needle bed 10,

while at thesame'time permitting-an unusually large number of suchneedlehelpers to be conveniently disposedwithin aunit of length of theauxiliary cr a needlebed 10.

This is rendered possible by means of the 7' p g .g ag1ng port on and aneedle engaging-p ortion spaced therefrom, sa 1d bed-engag1ng staggereddisposition of the'jacquard ca rd-: engaging ends 185 and 18! of therespective needle helpers 12 and;13, V-This arrange ment, of course,requires a newtype of jacquard card which,'howe v'er. is not apart ofthe present invention, beingpmoretully described and being fully claimedin; a'copending application filed of even date "here-- with and entitledCard for jacquard knite ting machines. It may besuf'ncient, how-l ever,here to state that the needle-helper en posed in separate rows, one rowof elements to be adapted to engage the jacquard end engaging portions18 of the series otfneedle helpers 12, and the other-row elements,

the nit eaten idea '13 the jacquard card-engaging portions 18" of theremaining series of needle helpers 13. i

The construction described above is sufficiently clear from theforegoing description. Likewise the manner of assembling and opemci emdevices described above will be readily apparentto those skilled. in theartto which the present invention relates. The fo regoing constructionenables the remarkablylcompact assembly of the needle helpersand thusthe disposition'of an unu'sually larg'ennmber of needle helpers within-aunit of length of the auxiliary needle bed 10 or the lik e thuspermitting a very fine and compact jacquard pattern to be knitted intothe fabric made by the jacquard knitting machine to hich the'construct-ion of the ,,presentinvention is applied. The devices ofthepresent invention are, at the same time, simple vin construction,easy and economical toifabricatmeasy to apply, and certain, con venientand. accurate, in operation. 1

no may here, be stated, by way or further explanation, that theauxiliary needle helpers ofth e present invention are also termed in theknitting art in which the same are. in

tended tobe employed needle jacks and are particularly adapted for usewith jac- ,quardsknitting machines, the forwardend of each needle helperor jack as it slides in its particular groove in the needle bed engaging the rear or butt end of its respective needle, While the, rear endof. each needle helper or. ack as it'slides in its appropriate grooveinflthe needle bed is engaged by the ,jacquard card orpasses through agrooveor slot 1n such card, dependlng on whether the particularneedlehelper or jack and thus the partici'1lar:' needle associated therewithis intendedto be operativeror leftin inoperative, position. j i b f Whatwe claim as our invention is 1.
